It is often considered as a variety of Taraxacum laevigatum (i.e., Taraxacum laevigatum var. erythrospermum).[3]

Description

This species is very similar to, and often mistaken for, the common dandelion, Taraxacum officinale. It most readily differs by its reddish-brown seed bases, unlike the more olive colored seeds of T. officinale. T. erythrospermum can also be diagnosed by its leaves, which have consistently triangular lobes throughout, whereas T. officinale tends to have erratic lobing with minimal or no triangular form. The leaves of T. erythrospermum thus bear a closer resemblance to the basal leaves of sow thistles (Sonchus oleraceus).
